RE: [xsl] Re: Reference to variable cannot be resolved.

Hi.
Bu then how the compiler knows wish variable is the right one?
i. e.,
if I have:
<xsl:variable name="x" select="1"/>
<xsl:variable name="x" select="2"/>

when I do:
<xsl:value-of select="$x"/>

what will appear? 1 or 2?

The second sentence is nonsense. Variable references are resolved to
variable declarations at compile time, the run-time behavior doesn't
care in the slightest what the original name of the variable was.
